The hospital that was the nexus of several storylines in the flash-sideways in Season 6 was the Nuuanu location of the Rehabilitation Hospital of the Pacific (226 North Kuakini Street). Jack and Juliet worked there, and patients included Claire, Locke, Sun, and Sayid’s brother. Visitors included Kate, Sawyer, Sayid, Nadia, Helen, and David. The location was also used to portray the care home where Anthony Cooper lived (“The Candidate, Ep. 6×14). (continue reading…)

The office building where Claire went to visit the adoption agency, and where Desmond introduced her to his lawyer Ilana (“The Last Recruit,” Ep. 6×13), was Pauahi Tower in downtown Honolulu (1001 Bishop St.). The lobby was transformed with a check-in desk and a sign that read “Constellation Tower.” Desmond and Claire took the escalator to the mezzanine level, then took the elevator to the 15th floor. Jack and his son David later arrived for the reading of Christian’s will. The mezzanine level also stood in for Heathrow Airport when Sayid was apprehended (“The Greater Good,” Ep. 1×21).

One of the final scenes of “LOST,” in which most of the characters came together in the flash-sideways before “moving on” (Ep. 6×17, “The End”), was filmed inside the St. Margaret Mary Chapel at Sacred Hearts Academy (3253 Waialae Avenue) in Kaimuki. It was the same church where the “Lamp Post” station was hidden (Ep. 5×05, “This Place Is Death,” and Ep. 5×06, “316”). The grounds of Sacred Hearts Academy were used for several exterior shots in the same episodes. (continue reading…)

The hospital where Sayid and Nadia go to see Omer, and where Jack is briefly seen passing in the hallway (“Sundown,” Ep. 6×06), was Hawaii Medical Center East, formerly St. Francis Medical Center (2226 Liliha Street). (continue reading…)

The bustling arrivals and baggage claim area of Los Angeles International Airport was filmed at the Honolulu International Airport, in and around Baggage Claim F (lower level, east end). This includes the small office where Jack and Locke meet, the tunnel and skylight Kate sees as she flees the building, and the pickup area where Kate jumps into Claire’s taxi cab. Note that the customs station where Jin and Sun are stopped is a different location. (continue reading…)

The intersection in La Brea, California, where Nadia was hit by a car, and where Jacob prevented Sayid from suffering the same fate (“The Incident,” Ep. 5×16), was on Auahi St. at Kamani St., just off Ward Ave. (continue reading…)
